ELECTRONIC HEAT PUMP F11ed Ju1y 28, 1954 ArrbR-Ey insulafjon isobtainable in practice and that Sone heat vvill be conveyed along theelectrical conductors then1- Selves Although I have Shovvn and describedSpeCic enbodin]ents of ny invention, I anl aWare that other n10difications theref are possible My invention, therefore, is not t0 berestricted except insofar aS iS necessitated by the prior art and theSpirit of the invention I Clainl aS Iny invention;

1. In a device 0f the class described, a rSt electrica1 conductor and aSecond electrical conductor of Supercon ductive T1aterial, Said Stconductor having a cTOSS-Sec tional area at least ten tillles as gfeataS the croSS-Sec tional area of Said Second conductor, the ends of Saidiil'st conductor being j0iled t0 the corresponding ends of Said Secondconductor, Ineans forlTling heat insulating chanlbers Sufrounding eachof the junctions between the first and second conductofs, Said deviceforIning a heat pulnp vvhen cutrent is passed through the conductors atSuperconductive ten1peratures 2. In a device according to clain1 1 Saidiirst and Sec Ond electrical conductors being hollow,

3. In colnbination, a first elongated conductor of a firstcroSS-Sectional area, a Second elongated Cohductor of a Secondcr()SS-Sectional area having the ends thereof joined to respective endsof Said TSt conductor, one junction being thermally insulated fron1 theother junction, Said first and Second conductors being c0mposed ofmembers of the group compdsing vanadium, zinc and gallium and beingsuperconductive bew a predeter- [ined tenperatufe and Said ISt Inaterialhaving a crosssectional circuxnference less tha1 0ne-tenth of thecrosssectional circumfefence of said Second conductor, a chan1 berprovided in the region of one of the junctions for holding a liquied gasin the region of that junction, sajd gas having a vapolizationtemperature below the temperature at vvhich Said conductors beconleSuperconduc tive, and direct current generating neaJ1S connected intern1ediate the ends of one of said conductors in Selies there with.

4. In conbination, a pair of e1ectrical conductots of naterial capableof being Superconductive, at least one 0f Said conductors being il theform of a honow shell and having a ct0sssectional area at least tentinles as great as the cr0SS-sectiona1 area of Said other conductor,the,

ends of said one conductor being j0ined t0 the ends of Said otherconduct0r, and direct current generating n1eans connected intern1ediatethe ends of one of Said conduct()TS in Series thereyvith TT1econlbination accofding t0 clain1 4 and further including means forIingheat insulating chambers Sllr Tounding each of the junctions between theiil'St and Sec0nd conductors 6. In a device 0f the class descIibed, a Stelectrical Conductor and a Second electrical conductor of IIaterialcapable of being Superconductive, Said iirst conduct01 having acroSS-Sectiona1 area at least ten tin1es as great aS the croSS-Sectionalarea of Said second conductor, the ends of Said rSt conductor beingj0ined to the corresponding ends of said Second conductor t( f0ITnjunctions, and difect current generating n]eans connected internediatethe endS Of one of Said conductors in series therewith Whereby vvhencurrent is passed through the c0nductoS an electron velocity change iSefected at Said junctions causing an energy radiation at one of Saidjunctions and an energy absorption at the other junction 7. Incombination: a rSt e10ngated conductor of a rSt cr0SS-Sectionalcircunference, a second elongated conductor of a second cr0SS-Secti()nacircun1ference less than one-tenth of Said first croSS-Sectionalcircumference, Said firSt and said second conductors conlprisingInaterials which are Superconductive belovv a predeterrnined ten]-erature, Said Second conductor being electrically connected to Saidfirst conductor on the inside thereof near the ends there0f, said secondconduct0r extending back along the inside of Said iirst conductor, in anencircling Tlanner about Said Second conductor, fof a distance at leastthree tifnes the thickness of Said second conductor, a direct currentgenerator connected in series vvith Said conductors and c00ling nleansin the region of one of the junctions between said conductors lefee1ceS(;ited il1 the e of this patent UNITED STATES PATENTS 413,136 Dewey 0ct.1 1889 94l,826 Taylor II()v. 30, 1909 1,804,072 I`lrrettini May 1931 2443 64l Ray Iune 22 1948
